Two dealers are telling me that they only put the 10W30 full synthetic in their motocross bike, but not the road bikes. They both encouraged me to use semi-synthetic oil. Of course you have to go to a different brand than Honda for that. Might just go back to regular Honda 10W30 and see if it gets back to normal as it was before the 600 miles service when the dealer put in the 10W40...Just a point of clarification. HONDA HP4 oil is a petroleum-synthetic blend. HP4S is full synthetic, HP4M is synthetic blend with Moly (friction modifier) added. The M is used in the engine side of CRF motocross bikes, for instance, and the regular HP4 in the gearbox/clutch side.
There are various training programs available to dealers through manufacturers. YAMAHA service training tells us that approximately 63% of what we tell a customer is processed (heard) and of that percentage only 52% is internalized (understood).
